Output System Connections

Single Module UPS Installation

6.Connect the system output cables between the UPS output (U2-V2-W2-N terminals) and the critical load and tighten the connections to 5Nm for M6 bolts, to 13Nm for M8 bolts or to 26Nm for M10 bolts. Ensure correct phase rotation.

External UPS Battery Connection (60kVA Models and Above, Option for 30-40kVA Models)

Connect the battery cables between the UPS terminals (+\-) and its associated battery circuit breaker. Observe the battery cable polarity.

NOTE

When connecting the cables between the battery extremities to the circuit breaker always connect the circuit breaker end of the cable first.

! WARNING

If the load equipment will not be ready to accept power on the arrival of the commissioning engineer, ensure that the system output cables are safely isolated at their ends.

Internal UPS Battery Connection (30/40kVA only)

7.The battery consists of a series string connection of 5 x 8 (or 10) x 12V 6-cell battery blocks.

a.Ensure that the eight (or 10) battery blocks in each tier (tray) are interconnected.

b.Connect the positive and negative cables to the UPS terminals.

c.Plug in the cables between the tiers.

d.Ensure correct polarity battery string series connections (i.e., intertier and interblock connections are from positive to negative terminals.

! WARNING

Hazardous Battery Terminal Voltage 480VDC

Ensure correct polarity of string end connections to the UPS terminals, i.e., positive to positive and negative to negative, but leave these UPS terminal cables disconnected until connection is authorised by the commissioning engineer.

Ensure correct polarity of string end connections to the battery circuit breaker and from the battery circuit breaker to the UPS terminals, i.e., positive to positive and negative to negative, but disconnect one or more battery cell links in each tier.

Do not reconnect these links and do not close the battery circuit breaker before authorised by the commissioning engineer.

8. Refit all protective covers removed for cable installation.
